Although he has six defeats on his card he is experiencing something of a renaissance under Pernel Whitaker. That said, he has been down in each of his last two fights.

Ten years ago Kostya Tszyu inflicted his first career defeat with a brutal, second-round knock-out.

Until then Judah was the ‘next big thing’. He had a big mouth and plenty to back it up with. He billed himself as a mini-Mike Tyson, the Baddest Man on the Planet II, if you like.

Tszyu knocked the stuffing out of him but not the bombast. He says it is gone now. Since his move to Las Vegas he has converted to Christianity and settled down.

He sees Khan as the vehicle back to the big bucks. Judah can punch. And he is fast, which is his biggest asset.

But he is vulnerable. And so is Khan, who has some way to go yet before he answers all the questions about his chin, if ever.

Khan has rebuilt ­brilliantly after that knockout defeat to Breidis Prescott. The more time he has spent in Los Angeles, the better he has become.

It was in the Marcos Maidana fight he showed how far he has come, flooring the Argentine hard nut with a stunning body shot in the opening round. And in the 10th he withstood that ferocious onslaught by one of the biggest light welterweight punchers. And he finished strongly, hurting Maidana with some big punches.

Khan is 24 and still improving. I’m not sure there is huge development in him technically, but he will get more experienced.

I reckon he is two, maybe three years off his peak. I don’t think he has a long career ahead of him. He turned pro too early to be boxing much into his 30s.

It’s all about the big fights for him now.

He knows better his own strengths and weaknesses and after Maidana will not be fazed by Judah at all.

Khan’s relationship with trainer Freddie Roach is the key to everything. I said after the Prescott defeat that there was only one place for Khan to go.

He obviously saw things the same way. His time spent at the Wild Card Gym has made him the fighter he is.

He wants to be a Hall of Fame fighter. And these are just the kind of bouts he needs for that.

The name he really wants is Floyd Mayweather. That’s ambitious but if he beats Judah and then Tim Bradley, it becomes a genuine fight, especially if the Manny Pacquiao bout cannot be done.

I see Khan coming through with a dominant points win tonight, maybe a late stoppage. Expect fireworks, because he could go over himself.
